    Morphological information is given on specimens of Raja georgiana that were caught during a demersal trawl survey in Subarea 48.3, South Georgia. It is concluded that, in spite of allometric growth, proportional measurements are best referenced to total length rather than disc width. Additional biological information is given: total mass=0.00000646x(total length)3.06. Based on data from male fish, they are thought to mature at about 800mm total length.
